I noticed Paste event.clipboardData could only paste a single copied file from the clipboard in Firefox (130.0.1), but Chrome (129.0.6668.70) and Edge could paste multiple files just fine.
I couldn't find if this was a known issue, and MDN Web Docs stated this feature as "Baseline widely available". So, could this be a bug, intended behavior or other?
